The U.S. military said Thursday that four more American military personnel have been killed in Iraq.

Three American soldiers were killed Wednesday night in a roadside bomb blast in Baghdad.  A U.S. Marine was also killed Wednesday during combat operations in the volatile western city of Ramadi.

The latest casualties came on the same day as the deaths of 14 U.S. Marines and their civilian translator in a bomb blast near the town of Haditha, northwest of Baghdad.  In total, 25 American troops have been killed since Monday.

Violence Thursday also claimed at least eight Iraqis in reported attacks across the country.

Against this bloody backdrop, Iraq's constitutional committee continued working to meet the August 15 deadline for drafting the country's permanent constitution.
